2027 Social Security COLA: Could Checks Rise by $75 a Month?

2027 Social Security COLA Forecast

Current forecasts point to an increase in Social Security benefits in the United States in 2027, after mid-2026 inflation data showed a slowdown from levels that had led some earlier estimates to project a larger increase.

The latest estimates range from 3.5% to 3.8%. AARP lowered its forecast to 3.5% on August 11, while The Senior Citizens League kept its estimate at 3.8% in July.

These figures remain forecasts because the Social Security Administration has not yet announced the official 2027 COLA.

Why Did COLA Forecasts Change?

Social Security benefit increase forecasts are tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), the index used to calculate the Social Security cost-of-living adjustment.

June 2026 data showed an annual inflation rate of 3.5%, prompting some analysts and organizations to lower their earlier forecasts. Some earlier estimates had reached as high as 4.7% before falling as newer inflation readings were released.

In July, AARP estimated the increase at about 3.6%, while independent analyst Mary Johnson lowered her forecast from 4.7% in June to 3.7%. On August 11, AARP lowered its estimate again to 3.5%.

Latest 2027 Social Security COLA Estimates

Forecasts differ among organizations tracking inflation and Social Security data. AARP estimated the increase at 3.5% in August, while The Senior Citizens League projected an increase of 3.8%. Mary Johnson's estimate was 3.7%, according to the latest information provided in the sources.

The differences show that the final percentage has not yet been determined and that any changes in inflation data during the remaining months of the third quarter of 2026 could affect the final calculation.

When Will the 2027 COLA Be Officially Announced?

The 2027 COLA percentage remains unconfirmed. The annual adjustment is calculated using CPI-W data for the third quarter, covering July through September, compared with the third quarter of the previous year.

According to the forecasts cited in the sources, the Social Security Administration (SSA) is expected to announce the official percentage on October 14, 2026, after the September inflation data are released.

Benefit checks reflecting the 2027 increase are expected to begin going out in January 2027.

How Much Could Retirees' Checks Increase?

The actual amount each retiree receives will depend on the value of their current benefit. According to an AARP estimate, a 3.5% increase could mean about $73 more per month for a retiree whose calculation is based on the average benefit used in its estimate.

Earlier estimates based on a 3.6% increase indicated a monthly increase of about $75, while some estimates based on 3.8% point to an increase of roughly $74 to $79, depending on the baseline benefit used in the calculation.

Therefore, the $75 figure should not be considered a guaranteed increase for every retiree, because the actual increase will vary depending on the value of each person's benefit.

Would the 2027 Increase Be the Biggest in Years?

If the final increase falls within the 3.5% to 3.8% range, it would be higher than the 2.8% increase in 2026 and also above the 10-year historical average of 3.1%.

The available data indicate that an increase between 3.5% and 3.8% would be the largest annual increase since 2023.

However, the actual impact of the increase on retirees' purchasing power also depends on living and health care costs, not just the COLA percentage.

Why Are Some Groups Calling for Changes to the COLA Formula?

Retiree advocacy groups are calling for changes to the way the cost-of-living adjustment is calculated, arguing that the CPI-W does not adequately reflect the spending patterns of older Americans, particularly health care costs.

Analyses by The Senior Citizens League indicate that retirees have lost about 13.7% of their cumulative purchasing power since 2010, according to the data provided in the sources.

Based on the information available here, there are no confirmed legislative actions to change the way COLA is calculated as of August 2026.

What Could Happen to the 2027 Increase Next?

The 2027 forecast will remain subject to change until the final inflation data needed for the calculation are released. That is why current estimates range from 3.5% to 3.8%.

The official percentage is expected to be announced on October 14, 2026, after which the exact increase can be determined more precisely based on each beneficiary's benefit amount.
